You have to actually be credited for the guide, not just named in it for a tip or two... for Marvel Pinball only StormtrooperMx19 and myself got credit, since I wrote everything and he contributed all those vids and details for numerous trophies. When people provide some tips the author will note the contribution, but you don't get an "official" credit unless you are listed as a co-author for the guide as a whole.
